[BUG] Passthrough audio changes sample rate on multiple audio streams

[potejan]

I agree. I think the main issue here is MediaInfo's and ffmpeg's handling of Type-1 AVIs. MediaInfo reports one audio stream (the real/interleaved stream), while the latter reports two streams (the interleaved stream and the timecode/metadata stream). Both seem unable to apply the timecode/metadata stream's sample rate onto the real/interleaved stream. Only VLC player appears to do that. Honestly though, this is an extreme edge case, since in almost all other videos the metadata of both streams matches anyway. I worked around this issue by converting my problematic videos back and forth using dvdate, which properly applies the correct sample rate to both audio streams. Then, I simply do "auto add (first)" in Hybrid, and I am done.

Fun discovery: Even with the proper Type-1 AVI produced by dvdate, the second audio stream is silent. This confirms my theory that it does not contain any audio content, but merely metadata.
